How to access the inner class from code within the outer class?

The inner class is instantiated only through the outer class instance.
class EnclosingOuter {
private int noInnerClass = 1;
public void getNoOfInnerClasses(){
           Inner in = new Inner();
System.out.println(“No Of Inner classes is : “+ in.getNoOfClassesFromOuter());
}
class Inner{

public int getNoOfClassesFromOuter(){ return noInnerClass; }

}
Here the method getNoOfInnerClasses() is called on the outer class’s instance through this outer class instance the inner class instance in is created.
